目的分析辽宁省锦州市生活饮用水卫生监督日常监测前后饮用水质量。方法于2015年5月—2016年5月,采用随机抽样法选取城区46个二次加压供水单位、2个企业自建水厂、2个自来水厂监督前105份水样和监督后180份水样,对生活饮用水卫生监督前、后水质监测情况进行调查,分析对比实施卫生监督前后的数据,对生活饮用水卫生监督管理应用效果进行分析。结果生活饮用水卫生监督实施后,末梢水合格率为81.54%(106/130)、出厂水合格率为98.00%(49/50),明显高于卫生监督前,同时供水建设率为95.00%(19/20),明显好于卫生监督前的70.00%(14/20),各项对比差异均有统计学意义(均P<0.05)。结论加强卫生监督日常监测可提高生活饮用水质量。
Objective To analyze drinking water quality before and after daily monitoring of sanitary drinking water in Jinzhou City, Liaoning Province. Methods From May 2015 to May 2016, 46 secondary pressurized water supply units, 2 self-built water plants and 2 waterworks were selected to supervise 105 water samples and 180 Water samples, drinking water before and after the health monitoring of water quality monitoring conducted a survey to compare the data before and after the implementation of health supervision, analysis of the application of sanitary drinking water health supervision and management. Results After sanitary drinking water supervision, the qualified rate of peripheral water was 81.54% (106/130) and the passing rate of manufactured water was 98.00% (49/50), which was significantly higher than that before health supervision and the water supply construction rate was 95.00% 19/20), which was significantly better than 70.00% (14/20) before the health supervision. The differences between the two groups were statistically significant (all P <0.05). Conclusion Strengthening health surveillance routine monitoring can improve the quality of life drinking water.
